SUMMARY
A field experiment was conducted during kharif season of 2016 at Udaipur, Rajasthan on clay loam soil to assess the effect of fertility levels (60 N+30 P2O5+30 K2O kg/ha, 80 N+40 P2O5+40 K2O kg/ ha and 100 N+50 P2O5+50 K2O kg/ha) on single cut genotypes (SPH 1725, SPH 1794, SPH 1797, SPV 2317, CSH 13 and CSV 21F) of fodder sorghum. Amongst genotypes, SPH 1752 proved most efficient as it gave significantly higher green (47.73 t/ha) and dry (14.24 t/ha) fodder yields, net returns (Rs. 41150/ha) and B : C ratio 1.60. The crop fertilized with 100 N+50 P2O5+50 K2O kg/ha recorded significantly higher green (41.08 t/ha) and dry (12.26 t/ha) fodder yield as well as net returns (Rs. 30803/ ha) over application of 60 N+30 P2O5+30 K2O kg/ha and 80 N+40 P2O5+40 K2O kg/ha.
Key words: Single cut sorghum genotypes, fertility levels, growth characters, fodder yield and economics
